The modified two-interstitial modelFunded under: JRC-FUSAFE 4C
From the many very controversial radiation damage models developed during the last 30 years only the modified two-interstitial model is in agreement with experimental and theoretical results. It is shown that the confusion in the past is due mainly to the use of steady-state solutions of simple rate equations, which do not reflect physical reality. Results of annealing experiments after irradiation with high energy particles and of radiation enhanced diffusion experiments are discussed and properties of point defects in fcc materials are derived. The finding that the migration activation energies of vacancies and of interstitials decrease considerably with increasing high energy particle flux is one of the most important features in the modified two-interstitial model.
